    Switch Contact Blocks

    Image of Product. Front orientation. Switch Contact Blocks.
    Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

    Vibration-Resistant Plastic 22 mm Panel-Mount Push-Button-Actuator Emergency Stop Switches

    A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications. These switches immediately cut power with a single push. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. These switches meet American, Canadian, European, and other global safety requirements. They’re rated NEMA 4X, NEMA 13, and IP65 for protection from corrosion, washdowns, and oil/coolant spraying.
    Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
    Continuous—Continuously illuminated switches stay lit once installed for high visibility in dark areas.
